摘　　要： 为了解不同水平竞走运动员的脑电α波特点,探讨其项目内稳态的EEG信号特征,利用高级运动训练监控仪采集5名健将级竞走运动员不同训练阶段56个样本的EEGα波数据,采用主成分分析和序参量理论提取竞走运动员SpSH所隐含的竞技水平信息进行统计分析。结果发现：状态优秀运动员SpSH品质明显高于状态一般运动员。说明竞走运动员EEGα波的序参量（优势频率10 Hz）可以表征其SpSH品质。 In order to understand the EEG α wave characteristics of race walkers at different levels,and to probe into the EEG signal characteristics of their sport-specific homeostasis,the authors collected the EEG α wave data of 56 specimens of 5 master race walkers at different stages of training by using an advanced sports training monitor,extracted competitive performance information implied in the SpSH of the race walkers,did a statistical analysis by means of principal component analysis and order parameter theory,and revealed the following finding： the SpSH quality of a race walker in excellent condition is significantly higher than that of a race walker in ordinary condition,which means that the order parameter（dominant frequency at 10 Hz） of the EEG α wave of a race walker may represent his/her SpSH quality.
